This invention relates to a new and useful improvement in calculating machines and is designed particularly as an improvement upon the combined adding .nd typewriting machine disclosed in French patent to Hubert Hopkins, No. 383,719.

My present invention contemplates means whereby numbers can be simultaneously registered in the front and rear totalizers;

simultaneously subtracted from both of said totalizers, which latter operation involves the automatic introduction of 1 into the units wheels of each register; and the control of the front and rear totalizers whereby In the machine of the French patent referred to, there are ten digit keys 0. and ten multiplier keys I). The ends of the digit keys lie under the ends of the vertical bars 56 (see Figs. 1 and 16), which, when elevated, will raise pins 63 in a pm carriage 57, said carriage being advanced step by step leftwardly as the eys are successively o erated. When the carriage has been advanced and the pins 63 therein positioned to represent a number, the o oration of the main operating shaft 106 wi 1, through suitable appropriate cams 82-409, lift the car riage and its elevated pins 63 to position pins 93 in a stationary field of etc 8 and place said pins 93 in control of rac bars 100 which are provided with shoulders 101 to engage said elevated ins. These rack bars 100 carry type at't 'eir forward ends which cooperate with printin hammers, whereby a record may be made 0 the various items on a sheet'of paper carried by the platen 4, such as amounts registered in the front and rear totalizers and thetotals thereof, the multiplicands set up in the machine,- the minuend and subtrahend, remainders, etc. 119 indicates the wheels of the forward totalizers, of which there may be several groups, and 268 indicates the wheels of the rear totalizer, which in the operation of multiplication are stopped leitwardly one higher space at the end of every operation of each multiplier key.

I shall not describe the carrying mechanism, or the multiplyin mechanism here, as the same are fully disc osed in the French patent referred to.

Referring now to Figs. 1, 3 and 4, it will be seen that the rod 113, which is connected to the frame 49 in which forward totalizer wheels 119 are mounted, is controlled by a cam 109 cooperating with a cam face tappet 112 mounted on the be r 113 in the same mannor disclosed in said French patent; also that the cam 82, which is connected to the cam-109 by means of a colla 182 slidingly mounted on the main operating shaft 81, also we crates with a bell crank lever 180- 181 in he manner described in said French patent (see Figs. 4 and 5), the cam 82 being employed to cooperate with the cam face tappet 140 mounted on the end of the rod 138 to rel-set the carrying segments after the same have been operated. Normally, when the machine of the French patent is operated, these cams 82-109 are located in the position shown in Fig. 4 wherein they control bars 113 and 138 to register numbers in the forward totalizer into a selected group of forward totalizer wheels and also re-set the carrying mechanism which cooperates with the forward totalizers.

In the French patent, aforesaid, the de pression of the D. or decimal key, in addition to other functions which it performs. would shift the cams 82-409 from their first position, here shown in Fig, l, to their third position, in which cam 105 would be placed in control of a tappet 27;, on a bar 272 connected to the frame in which the l( .u totalizer wheels were mounted, so as to bring the rear totalizcr wheels into mesh with the racks without disturbing the position of the forward totalizer wheels. The cam 82 would also be shifted to its third position and put in control of the tappet on a bar corresponding to the bar 138 whereby the carrying mechanism for the rear l'otalizer wheels would he re-set.

The second and neutral position of lllU- cams 82-101l is that position in which the cams may he rocked when located between the pins on tuppcts 1l2i273, etc, as when the 'l'. or total key is dc 'n'csscd.

My present invention contemplates the all-- dition of a third cam which I will designate as 82 and which is like the cam 82 in many essentials with the exception that it is moved longitudinally of the shaft 81 independently of the cam 109, with which it has no con nection. and by independent means.

Referring now to Fig. 6. which is an iso lated View of the parts controlled by the E. or extension key. I will state that the pur pose of this key to cause a number scl up i on the keyboard by depressing the digit keys, to he set up or represented by Lin, pendants 235 (see Figs. 1 and 2) so that said number can be either used as a multiplicand or a snbtrahend. \Vhen the E. key is depressed in thispresent instance, it moves the cams 82 109 to their second or neutral position so that the number to be used as a multiplicand or subtrahend is not introduced into either the front or rear totalizer wheels and said extension key also shifts the cam 82 laterally beyond control ofthe pin on the tappet of bar 272 or to the position shown in full lines in Fig. 4. The extension key is connected by a bell crank lever to a rod 325, in turn connected to a lever 326, but said lever in this instance is not provided with a forward extension to depress a bar 185 and thereby disable the carriage lifting mechanism, as it is desired that said carriage liftin mechanism: shall be operated to control t e racks as in the normal operation of the machine. The lever 326 is connected by a link 328 to a bell crank lever 329 which, in this instance is notprovided with a forward extension to depress the bar 113 as it is not desired to introduce a number set up on the keyboard and extended back into the pendants, into the forward totalizer wheels 115); nor is the rearward extension 331 of this lever notched under the member 180 of the bell crank as in the French patent, butsaid rearward extension engages said men'lbcr 180 and shifts the cams St. and 10%) to their central or neutral position as before described. The lever 331 also engages a pin on the end of an arm .221 so as to rock the shaft "220 and through the medium of the plate 219 lift the supplemental bars 102 so that the notches in. their upper ends will engage the pins 217 on the main levers 102, which latter are ronncctcd lo the racks whereby the supph-u'u-ntal bars 102 partake of the movement of the racks so as to locate the pendants 235 in the manner conten'iplated by said French patent.

in my present application there is a lever 500 whose end lies over the extension 33]., said lever being in the form of a bell crank lever (see Fig, l) pivoted on a post mounted in the base of the machine and the upward extension 501 is connected by a link 502 to a lever 503 whose upper end engages the hub of cam 82. In this manner, when the extension key is depressed, the cam 82 is shifted beyond control of the rear totalizer carrying mechanism. Mounted on shaft 106 is a two part lever 5()'l-505, the portion 504 lying over the lover 500 so that when said lever 500 is raised, it will, through a spring 501') more a link 5107 downwardly so as to elevate thcfiorward hooked end of a lover SOS nt of the path of a pin 509 on ram 32, The purpose of making this lever Sui- 505 intuo parts which are connected by a spring, is to enable the part 504 to be raised independently of the part 505 in certain operations of the machine where the part 505 is locked against movement, and also, in the operation of the machine, when the pin 509 engages the hooked end of lever 508 to pull the same forwardly, the sprin 506-wil1 yield to permit this slight fol-war movement, although the forward end 504 1.0 of. the lever is prevented from moving downwardly. The hook lever 508, before referred to, is pivotally mounted upon an arm 510, which arm is supported y the shaft 106 and carried at its upper end a 5 cam bar 511 having a hooked forward end, said forward end and cam face on said bar coiiperating with the in 2'72 on the bar 272 (see Figs. 3 and 4; Thus, in the normal operation of the machine, when the cam 82 rocks forward, the bar 272 will be depressed simultaneously with the depression of the bar 113 and the rear totalizer wheels will be engaged with the racks 100 and disengaged therefrom at the same time that the orward totalizer wheels are engaged and disengaged from the racks, whereby a number set up on the keyboard through the digit keys wi 1 be simultaneously introduced into both the forward and rear totalizers. Thus the cam 82 is shifted to prevent a number, being extended, from being introduced into the forward totalizer wheels, and also to prevent said number bein introduced into the rear totalizer whee s when the E. or extension key is depressed, b the hook lever 508 which has its forwar end elevated out of the path of the pin 509 on the cam 82.,

In further describing the operation of the so-called result. keys, I shall take them up in the order that they occur in the machine, having commenced with the parts controlled by the E. or extension key which are located at the extreme left hand side of the machine.

The next 'key in order is the front register key. The key bearing the designationfFront reg. controls the parts next adjacent those. controlled by the E. or extension key which are best shown in Fig. 10. Briefly stated, the function of the front register key is to position the cam 82 so that a numberset up on the digit keys will not be introduced into the rear register but only introduced into the front register. The depression of the front register key through its connected rod 512, lever 513, link 514, and bell crank 515, raises, by the rear extension 516 of the bell crank lever, the memher 500 of the bell crank which shifts the cam 82 to its idle or non-controlling posi- 131011. I The rear extension 516 is notched so that a theilmember 180 of the bell crank 180-181 ot be moved cams 82-109 are left in their normal or first position. The operation of the bell crank 500501 will also raise the hook lever 508, as just above described, so that the rear totalizer wheels will not be brought into mesh with the racks.

The next in order of position from the left hand side of the machine is the T. or total key, which, like the T. or total key of the French patent has the function of shifting the cams 82-109 to their second or neutral position, but in the present instance, the T. or total key performs additional functions.

Referring to Fig. 8, it will be seen that the rod 170 connected to the T. key is also connected to the bell crank lever 172 and that this lever will, when operated, depress the rod 185, lifting the tappet 84 out of the path of the pin 83 on the cam 82, thus disabling the carriage lifting mechanism when the T. or total key is depressed. The bell crank 172 is connected by the link 17 4 to the bell crank 173 having a forward extension to engage a pin on the lower end of rod 113 so as to engage the forward totalizer wheels with the racks as is ordinary in totaltaking operations. The T. or total key in this instance, however, possesses the additional function, through the medium of its rear extension 179, of rocking the shaft 220 so as to lift the supplemental levers 102*to their intermediate position, but not so high as to engage the pins 217.

When the rearward extension 179 rises, it Will also rock the bell crank 500501 and shift the cam "82 out of control of the rear totalizers, at the same time rock a bell crank lever 312 (see Fig. 8*) so as to shift cam 317 slidingly mounted on shaft 106 into the path of movement of the pin 3-18 on a downward extension of cam 82 whereby the arm 314 will be rocked and the restoring bar 315 will engage the extensions 316 on the supplemental levers 109". In this manner, the pendants 235, see Figs. 1 and 2, are restored to normal or zero position whenever the total key is depressed and the machine operated. The restoration of the pendants in the machine of the French patent referred to, follows the depression of the P. or product key, butas the pendants in the present machine also represent subtrahcnds as well as multiplicands, I prefer to restore them following the operation of the total key. It is obvious that the P. or product key could also be used in the same manner to restore the pendants, asdescribed in said French patent, but in the present instance the P. or product key does not possess this function.

It will be observed from the operation above described that the depression of the total ke will cause the number registered in a seected group of forward totalizer wheels to be yielded as a total, whether this number represents the accumulation of a scrics of products, remainders, or a total of a series of items directly introduced into the front totalizer wheels. If a number is re resented in the rear totalizer wheels, it Will not be disturbed by the operation of the machine after depression of the T. or total key; but the pendants, formerly representing a multiplicand or subtrahend will be restored.

The next result key and its associated parts to be described perform practically the same functions of the D. or decimal key of the machine of the French patent in that when this key is depressed and the machine operated, a number set up on the keyboard will be introduced into the rear totalizer to the exclusion of the forward totahzer. The

rod 1H0 (see Fig. 7) which is connected to this key is also connected to-lever 3-11 in turn connected by link 3-12 to the bell crank lever 3l3 having a rearward extension 348 lying under the member 180 of the bell crank lever and the member 500 of the bell crank lcvcr 500-501 so as to shift the cam 82 to its idle position at the time that the cams 82109 are shifted to their third position. The hooked end of lever 508 is also elevated out of the path of the pin 509.

By refcrrinp .0 Figs. 5 and 7, it will be observed that. the bar 342 connected to the D. key is provided with a downwardly extendinn lug located at about midway its length which cooperates with the lower and outwardly extending end of a pivot-ed bail member 345, which bail member is utilized to slide the arm 10?" which controls the release of the printing hammers, so as to cause the same to remain in operative relation with its operating cam 82 substantially in the manner set forth in said French patent. This bail member 345 (see Fig. 3) also slides the arm 85 carrying the tappet 84 so as to maintain operative relation between cam 82 and said tappet when the cams are moved to their third position on the depression of the 1). key.

The bail member 3-15 has a bar 345 pivotally connected-to its inner end, which bar is mounted in a slot in the upper end of the post, said post being mounte the machine and forming also a support for the pivoted end of lever 503, see F ig. 4. The rear end of this bar 3-15 is provided with a cam face shown in dotted lines in Fig. 5 as a compound curved face, which cam face coiiperates with a slot in the shifting lever 503 which controls the cam 82. The purpose of this cam bar is to hold cam 82 in its shifted position shown in Fig. 4: when the bar 345 is moved rearwardly and relieve the bell crank 500-501 from strain.

The next series of parts under control of a result key are similar in some respects to those controlled by the P. or product key of the machine of the French patent. In

in the base of.

this instance, as the number represented in the rear totalizer may be a product result ing from nulltiplying operations of the ma chine, a minuend, or a remainder, I prefer to designate the key controlling the parts about to be described as rear total" instead of P. or product key of the French patent, to distinguish it from the usual T. or total key operated to obtain a total from the for ward totalizers. This rear total key is connected to a rod 302 (see Fig. 9) in turn connected to a bell crank lever 303 which has a forward extension to depress the bar 185 and disable the carriage lifting mechanism. Link 305 connects 303 with bell crank lever 30? having a forward extension to engage a pin on the lower end of the bar whereby the rear totalizer wheels are brought into engagement with the racks. This bell crank 307 also has a rearwardextension to rock the bell crank 500-501 so as to move the cam 82 to idle position and also to lift the hooked end of the lever 508 out of the path of the pin 509. .It will be observed that when the rear total key is depressed and the machine operated, that the number rcprescnted by the endants will not be canceled, but will still stand and the pendants remain in their former or. set position. This is desirable in some instances for the reason that a number represented by the pendants as a multiplicand can be ifie matedly multiplied by multipliers containing different digits without necessitating the repeated setting up of the same mnltiplicand. A number represented in the rear totalizer wheels when the rear total key is depressed, will be transferred into the forward total izcr wheels and a record made thereof. The T. or total key for taking a total from the forward totalizers and the rear total key for taking a. total from the rear totalizer will rise at the and of the forward stroke of the operating shaft. and said totalizcr wheels will stand clear at the end of total taking operations. If said keys are held depressed on the return stroke of the shaft. the total, or number previously represented therein, will be introduced into said wheels.

From the above, it will be seen that in the normal operation of this )resent machine, a number set up by the digit keys wi l be simultaneous] introduced into the front and rear tota izer wheels; that a total can be taken from either the front or rear totalizer wheels to the exclusion of the other by depressing the T. key and taking the total represented in the front totalizer wheels, or by depressing the rear total key to take the total represented in the rear totalizer wheels; that a number can be registered into a selected group front totalizer wheels to the exclusion oi the int-er totalizer by depressing the front register key; or anuniber can be introduced into the rear the subtrahend, set upon the in operations of subtraction a number up peering in either forward or rear totalizer wheels will be represented .as a minuend and a'subtrahend subtracted therefrom will reduce the numbers in both the front and rear .totalizers unless some means is provided to prevent this.

Subtraction as carried out in the machine shown in the accompanying drawings is substantially the same as that disclosed in an application -filed by Hubert Hopkins May 11, 1908, Serial Number 432,166, and an a plication filed March 29, 1912, Serial umber 687,200, in which a subtraction plate 407 arranged at the rear of the machine (see 3 and 13) is em loyed. This subtraction plate is controll by a subtraction key bar 451 having a button at its forward extremity, not shown whereby the same may -be operated. The bar 451 is connected to a lever 405, the up er end of which is normal) under a piv lever 406 carried by thesu traction plate. The mannor of operating; this subtraction plate forms no part of-niy ,present invention, and I will not, therefore, 'further describe the same exce t to'mention that when the subtraction p ate is lifted a pin 409 carried at its upper end operates a lever 410 connected by t e rod .411.to a lever 412. This lever 412 is pivoted to a cross bar 418 in the upper frame-plate of the machine see Fig. 1), and whenever the subtraction p ate is raised, willtrip the latch bar 127 in the units columnof the rear -totalizer wheels 268, adding 1" in the units totalizer wheel in the operof subtraction. As numbers are simultaneouslyintroduced into the wheels 119 and 268 in the normal operation of-the present machine, it is desired that the ordinary operation of subtraction shall simultaneously reduce the numbers represented by both sets of wheels 119 and 268. In other words, both front and rear totalizers become minuend registers in the operation of subtraction and ndants 235, will be subtracted therefrom saving a remainder in both sets of wheels.

In order that 1 may be automatically added in the units column of the wheels 119,

I arrange a lever 414 (see Fig. 4), one end ever the forward end of the latch bar 127 is raised, the rear end of the latch bar 127' is depressed, both latch bars being thus released so as to add 1 in the units columns of the wheels 119 and 268.

In certain operations of the nun-lune. it may be desirable to subtract in wheels :68 to the exclusion of the wheels [19 and tin-re fore, under such conditions, it would be impro r to add 1 in the units column of the wheels 119.

As the operation of the D. key will shift the cams 82109 to their third position, at the same time lifting the hooked end of lever 508, I utilize this movement. to disable lever 414 with respect to the latch bar 1'37. A rod 415 is connected to the rear end of lever 508 and to a lever 416 pivoted upon a post extending from the cross bar 413. The end of this lever 416 is provided with a. cum face which engages the lever 414. Lever 414 is slidably mounted on its fulcrum shaft and is held against a collar on said shaft by means of a compression spring 417. Thus when the lever 416 is operated, the lever 4-14 is slid longitudinally its shaft, which movement disengages its end from the latch bar 127 but does not remove the opposite end of said lever from between the latch bar 127 and the lever 412. Thus, if it is desired at any time to subtract from a number represented in the wheels 268, the D. key may be depessed and then the subtraction key operate In Fig. 4", I have shown a modified form of lever 414 which is capable of being moved in opposite directions for the purpose of selectively adding 1 in the units column of the wheels 119 or 268 depending upon which totalizer contains the minuond to be subtracted from. This modified form of lever numbered 414 is provided with extensions at its ends and springs on each side thereof whereby it normally coiiperates with both latch bars 127 and 127*. If the lever 414 is moved downwardly, as by a lever similar to 416, its left hand extension will be disengaged from the latch bar 127 and its right hand extension remain in engagement with the latch bar 127, whereas, if said lever is moved upwardly, its'right hand extension will be disengaged from the latch bar 127 and its left hand extension remain in engagement with the latch bar 127".

The means for moving the lever 414 upwardly is preferably connected to the front register key-and may be in the form of the lever 416, which will be oppositely dis osed to the lever shown in Fig. 4. I have s own a lever 416 for moving the lever 414 downwardly, and a lever 416 for moving the same u wardly.

In F1 5. 11 and 12, I have shown a novel means 0 operating the nonprint mechanism which becomes ciiective when any of the mul-
